This device contains circuitry to protect the inputs
against damage due to high static voltages or electric
field; however, precautions should be taken to avoid
application of any voltage higher than the maximum
rated voltages to this circuit. For proper operation, Vin
and Vout should be constrained to the range:
VSS<(Vin or Vout)<VDD
Unused inputs must always be tied to an appropriate
logic voltage level (either VSS or VDD).
